Setting Up a Block Transfer

Configure PanelView block transfers using the Block Transfer
dialog, which is accessed from the Communication Setup dialog.

For each block transfer (1 - 10), specify the parameters below:

Parameters

Description

Enabled

Enables or disables the block transfer.

Address

Specifies starting address for the block transfer read or write.

Mode

Specifies R for a Read operator or W for a Write operation.

Length

Specifies the number of words (1 to 64 ) to transfer. The
length 63 is reserved for Pass-Through.
Each block transfer read must be a unique length and each
block transfer write must be a unique length. However, a read
and write block transfer can be the same length.
The PanelView uses the length to identify data blocks.

Pass-Through

Enables or disables Pass-Through for application transfers
between a computer on the DH+ network and a PanelView
terminal on the Remote I/O network.
Pass-Through is a dedicated block transfer fixed at 63 words
in length.

Block Transfer Timeout

Specifies a timeout value for block transfers. A value of 0
disables the timeout.

Each block transfer requires a corresponding Block Transfer Write
(BTW) or Block Transfer Read (BTR) instruction in the ladder
program for the controller. The Address and Length settings must
match the Data File and Length settings in the instructions.
